SASH.

SPECIFICATION forming part of Letters Patent No. 260,873, dated fuiy i1, Issa. Appncnon niet Aprn 21,1882. (No model.)

To all whom t may concern:

Beit known that I, GEORGE H. JOHNSON, a citizen ofthe United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Sashes, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to devices for prevent- Ing rattling` and consequent wear in windowframes and the like," especially when the latter are in carriages or other vehicles.

It has for its object to protect certain parts from wear and to prevent the sash or frame .I5

from rattling in the easement; and with these ends in view my invention consists in attaching to the sides ofthe frame'or sash a strip of molded vulcanized rubbery or other suitable material of a breadth greater than the thickness ofthe sash or frame and of a length greater than that of the sash in Order that the strip may project below the bottom surface of said sash, all of whichwill be presently and in detail explained.

In order that those skilled may more fully understand the construction andoperation of my improved device, I will proceed to describe the same in detail, referring by letters to the accompanying drawings, in which-- Figure l is a side elevation of a sash with my improvement attached; Fig. 2, a top view of the same, and Fig. 3 a modification showing the strip attached to the sash in a serpentine manner.

Similar letters denote like parts in the several figures.`

A is the strip, which is made preferably of vulcanized molded rubber, although any other material of a vsuitable nature-such as feltmay be used with similar results. This strip A is attached', as shown, to the sidesof a frame or sash, B, by screws.

In a coach the windows usually slide up and down in a casing, and the frame of said window is covered with cloth, paint, or any suitable covering. This frame fits in the casing loosely in order that the sliding movement may be free. Use has demonstrated that the cloth or paint chafing against the sides ofthe casing soon wears out and becomes ragged and unsightly, and as a consequence there is a noisy and disagreeable rattling.

As heretofore set forth, the width of the strip A being greater than the thickness of the frame or sash B proper, the latter does not touch the casing, since the bearing or friction is on the rubber strip; also, thelength of said strip befinglonger than and projecting below the frame,

the projecting excess forms a cushion which protects-said frame on the under surface as against any j ar or contact with the casing.

It will be readily understood that 'by the use of my improved strip Iprotect the sash orl frame at -three points of contact; also, there is no rattle or noise, and being thus protected Vlar or not uniform in'width.

I am aware that U-shaped guards or pro tectors have been applied to sash-frames, carA riage-doors, and the like for the purpose of preventing wear on the faces of such frames or doors; also, that it is not new, broadly, to mold rubber into strips and apply the same as fenders or bumpers on doors, &c., and do not wish to be understood as claiming any such construction; but

What I do claim as new, and wish to secure by Letters Patent, is

1. A window-sash frame or similar device provided at its sides with independent and detachable strips of yielding material, said strips being wider than the thickness of the frame and projecting below the sides of the same, substantiallyas set forth.

2. The strip A, lof yielding material, formed and applied as describcd-that'is to say, projecting beyond the faces of` the sash throughout a part or the whole of its lengthin combination with a sash or frame, whereby the latter shall be protected as against wear from contact with the casing, substantially as land for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE H. JOHNSON.
